An important consideration in design of armed tactical VTOL aircraft systems should be the requirements for sustained low speed flight with good agility. Some maneuvers involved in attaining agile performance at low airspeeds absorb substantial power. Analytical results are presented for five armed tactical VTOL aircraft for those low speed maneuvers that are most power dependent. These maneuvers are acceleration and sustained load factor. Sustained maneuvers prohibit the use of stored energy by any of the propulsion systems.
